Simulating Sunyaev-Zel'dovich intensity maps of giant active galactic nucleus cocoons

Sunyaev–Zeldovich Effect

The Sunyaev - Zeldovich Effect

During passage through a cluster of galaxies some of the photons of the cosmic microwave background (CMB) radiation are scattered by electrons in the hot intracluster (IC) gas. The scattering slightly modifies the incident Planck spectrum, imprinting on it a unique spectral signature that was first described by Sunyaev & Zeldovich (1972). [The impact of hypothetical hot intergalactic gas on the...

Sunyaev-Zeldovich Contributions from Early Supernova Winds

The purpose of this research was to determine the contributions to the Sunyaev-Zeldovich effect from supernova winds at high redshift. In order to accomplish this, the shells were modeled individually to study the dependance of their behavior on the basic input parameters of the system, such as initial redshift and initial dark matter halo mass, especially at asymptotic bounds. Finally, the Com...

Cosmology with Sunyaev-Zeldovich observations from space

In order to assess the potential of future microwave anisotropy space experiments for detecting clusters by their Sunyaev-Zeldovich (SZ) thermal effect, we have simulated maps of the large scale distribution of their Compton parameter y and of the temperature anisotropy ∆T/T induced by their proper motion. Our model is based on a predicted distribution of clusters per unit of redshift and flux ...

Sunyaev - Zeldovich decrements with no clusters ?

Sunyaev-Zeldovich decrements in the temperature of the Cosmic Microwave Background (CMB) are produced by Thomson scattering of the CMB photons by the confined hot electrons in the Intra-Cluster Medium encountered along the line-of-sight. In this paper, we propose an alternate physical process that can produce detectable thermal and kinematic Sunyaev-Zeldovich decrements around quasars or quasar...
